Line choke
 Install the line choke between the radio interference filter and the sine
filter.
Radio interference filter
 The Load terminal of the radio interference filter is to be wired to the AEC
side, the Line terminal to the mains side.
Connection conditions
The system is to be installed, considering the applicable directives and
regulations, in a way that guarantees that it is suitable for parallel operation
with the local mains and that disturbance of the local mains or the systems of
other customers is impossible.
 The AEC must be connected to the mains such that it can be disconnected
from the mains by means of disconnecting elements (e.g. main switch,
contactor, circuit breaker)
 While the system is operating, disconnection of the frequency inverters
connected to the DC-link terminals of the mains unit is only possible by
means of appropriate DC switches.
 Use all-current sensitive circuit breakers or circuit breakers with adjustable
tripping delay.
The conditions for connection of the AEC mains unit to the local mains depend
on the safety equipment installed and/or the switch point implemented.

 Only use the AEC mains unit in combination with a sine
filter.
Sine filters with a relative short-circuit voltage of uk = 8%
are available as an accessory.
 Connect the sine filter such that the inductances of the sine
filter are on the terminal side (L1, L2, L3) of the mains unit
and the capacitances of the sine filter are on the mains side.
